Gold in dot matrix printers

Took apart some old dot matrix printers. In the printer head is these boards with gold in them. Just something to look out for.

Ha! Try looking up dot matrix on Ebay. I have a guy trying to give me some of them but I'd have to drive 25 miles there to get them. Might go ahead and do it if I can get ahold of him tomorrow.

those corner spots w/ the holes in the are gold or copper? i see spots like that all the time on different types of boards. if they are gold are they always gold or does it vary? thanks

the corners are gold if they are a gold color, if they are a darker color its copper, its pretty easy to see the difference when you put 2 side by side

what did you wind up doing with those boards ?

is this all gold?

I got some 'Star' brand dot matrix printers once, they have been my only sorce of whitee ceramic chips so far.
NZ was a bit behind the USA... No rocket ships etc etc.

I broke a plastic chip and under the plastic the legs were gold plated. But the visible part of the leg wasn't. Weird.

Old school electronics rule as gold was $30 a ounce in 1968......

And every key on the keyboard was a gold plated, platinum plated tip reed switch.....

i was stripping a server power supply unit today

came across these gold coloured pins at the edge:
